Aircraft model

XP-47J

This is the sole prototype of the 'Superbolt', a lightened and modified P-47D-20-RE. This aircraft retained the 2100 hp Pratt and Whitney R-2800-61 radial engine, but housed the powerplant in a very closely cowled and fan augmented housing. A separate ventral intake for the CH-5 Turbo-supercharger was also a feature. This aircraft achieved a speed of 504 mph. in level flight in August 1944.
